Wow, someone really cared that the kids had a great place to "play" I love it..and I think it's a great idea that you took this photo. I love the angle..I just the building wasn't behind it, maybe next time you might try angling a bit differently so the building wouldn't show, well, that is if you go back again.Maybe squat down or up a bit more.
But try this at other playgrounds..nice idea..different.Verena
